APPARATUS AND METHOD FOR TRANSMITTING AND RECEIVING SIGNAL IN A COMMUNICATION SYSTEM

摘要

A signal transceiving device in a communication system and a method therefor are provided to offer a space time frequency block coding method which prevents the deterioration of performance on a high-speed fading channel and a frequency-selective fading channel while a transmitter can communicate with plural receivers. A transmission signal generator(400) comprises as follows. A demultiplexer(405) divides an information symbol according to the number of transmission antennas. Repeaters(407,409) receive the divided signals to repeat the signals as much as preset frequency of repetition. Signal processors(411,413) perform frequency space block coding processes for the repeated signals. Phase vector multipliers(415,417) multiply phase vectors corresponding to each receiver by the signals applied with the frequency space block coding processes.
